Poisson Probabilities are a matter of plugging into the formula.
n = 6/2 hours = 3 per hour
Calculate it. Let's see what you get.
For the second, Poisson Wait Times are Exponential. Let's see what you get.
The arrival of trucks on a receiving dock is a Poisson process with a mean arrival rate of two per hour.
(a) Find the probability that exactly 6 trucks arrive in a two-hour period.
(b) Find the probability that the time between two successive arrivals will be more than 3 hours.
Please help me in solving the above problem!!!!
